stereographic, conformal or equal angle projection
Scales the radius by tan(theta/2). Preserves angles and maps circles to circles, which is what makes it the usual choice for crystallography.
Syntax
sP = eangleProjection(sR)
[x,y] = sP.project(v)
v = sP.iproject(x,y)Input
| sR | sphericalRegion the projection is restricted to |
| v | vector3d |
| x, y | plane coordinates |
Class Properties
| sR | sphericalRegion the projection is restricted to |
| pC | plottingConvention, which direction points east |
| antipodal | identify v and -v |
